A Grandiosity Bubble is an imagined, self-aggrandising, narrative involving the narcissist and elements from his real life â people around him, places he frequents, or conversations he is having. The narcissist weaves a story incorporating these facts, inflating them in the process and endowing them with bogus internal meaning and consistency. In other words: he confabulates â but, this time, his confabulation is loosely based on reality.
